Abstract

An illumination Device (DE) is fitted to a vehicle which comprises an analysis device which analyzes a Zone (ZA) located in front of the vehicle. The lighting Device (DE) comprises: a first light source (S1) generating first photons, and a mirror (RP) reflecting the first photons towards the Zone (ZA) so that the first photons form a first light beam (F1) ensuring a photometric lighting function; a second light source (S2) installed in front of the central Portion (PC) of the Reflector (RP) and generating a second photon; a Lens (LF) interposed between the second light source (S2) and the Zone (ZA), positionable at different positions and forming, by the second photons, a second light beam (F2) which is narrow and directed towards a sub-area of the Zone (ZA) which varies according to the determined lens position; and a control device (MC) which determines the lens position when an obstacle is detected in a subregion whose position is known.

Description

Lighting device with a main light beam and a narrow light beam that can be directed according to the position of an obstacle detected in front of the vehicle
Technical Field
The present invention relates to vehicles, optionally of the motor vehicle type, and more particularly to lighting devices equipped to such vehicles.
Background
Some vehicles, generally of the motor vehicle type, comprise at the front two primary lighting devices, for example of the meeting light (low beam), fog light or high beam type, responsible for ensuring a primary photometric lighting function, and at least one secondary lighting device responsible for dynamically illuminating, by means of a directable narrow beam of light, the obstacles in front of these vehicles detected by an on-board analysis device. The illumination of the obstacle (optionally a living body) is intended to draw the driver's attention to the obstacle, and thus allows the driver more time to perform an operation for avoiding the obstacle. Such auxiliary lighting devices ensure the function sometimes also referred to as "marker lights" and described, for example, in patent document EP 2420986.
The main disadvantage of this auxiliary lighting is that it adds to its volume, weight, power and control wiring harness, and price, and therefore can only be installed on certain relatively large space, relatively expensive vehicles. Furthermore, the presence of auxiliary lighting devices other than the primary lighting device may affect the styling of the vehicle.
Disclosure of Invention
The invention aims in particular to improve this situation.
To this end, the invention proposes in particular a lighting device intended, on the one hand, to be fitted to a vehicle comprising analysis means for analyzing an area located in front of the vehicle; and in another aspect, the illumination device includes a first light source that generates first photons, and a mirror that reflects the generated first photons toward the region such that the first photons form a first light beam that ensures a photometric illumination function.
The lighting device is characterized by further comprising:
-a second light source mounted in front of the central part of the reflector and generating second photons;
a lens interposed between the second light source and the area, the lens being positionable in different positions with respect to the mirror and forming a second light beam by the second photons generated, the second light beam being narrow and directed towards a sub-area of the area, the sub-area varying according to the determined lens position; and
-control means for determining the lens position when an obstacle is detected in a sub-area whose position is known relative to the coordinate system of the vehicle.
Thus, a lighting device is obtained which ensures not only a main photometric lighting function but also an auxiliary photometric lighting function of the marker lamp type (with a directable narrow light beam), the volume of which lighting device does not increase significantly with respect to a lighting device without marker lamp function.
The lighting device according to the invention may comprise further features which may be employed individually or in combination, and in particular:
the first light source of the lighting device may be mounted on the upper part of the reflector;
the second light source of the lighting device may be mounted in a vertical position with respect to the central portion of the reflector;
when the second light source does not generate the second photons, the control means of the lighting device may determine the position of the lens away from the passing trajectory of the first light beam, to "rest" the lens;
the lighting device may comprise a support member, which is fixedly connected to the lens, and a motor for driving a shaft, which is fixedly connected to the support member, into rotation. In this case, the control means of the lighting device determine the angular position of the axis, which varies according to the known position of the sub-area and defines the lens position;
the photometric lighting function may be selected from the group consisting of a low beam function, a fog light function, and a high beam function.
The invention also proposes a vehicle, optionally of the motor vehicle type, comprising analysis means for analyzing a region located in front of the vehicle, and at least one lighting device of the above-mentioned type.
For example, the vehicle may include two lighting apparatuses installed at the right-side front portion and the left-side front portion, respectively.

Detailed Description
The invention is intended in particular to propose a lighting device DE having a primary photometric lighting function and an auxiliary photometric lighting function of the marker lamp type and intended to be fitted to a vehicle V comprising an analysis device MA responsible for analyzing the front part of the environment of the vehicle V.
In the following, by way of non-limiting example, the vehicle V is considered to be a motor vehicle type. This relates, for example, to an automobile, as shown in non-limiting manner in fig. 1. The invention is not limited to this type of vehicle, however. In fact, the invention relates to any type of vehicle that can travel on a land lane.
In fig. 2 and 3, the direction X is a so-called longitudinal direction since the direction X is parallel to the longitudinal side of the vehicle; since the direction Y is perpendicular to the longitudinal sides of the vehicle V and therefore to the longitudinal direction X, the direction Y is a so-called transverse direction; and the direction Z is a vertical direction perpendicular to the longitudinal direction X and the lateral direction Y.
A road comprising a first lane VC1 and a second lane VC2 is schematically and functionally shown in fig. 1. A vehicle V, which comprises an environment analysis device MA and at least one lighting device DE according to the invention, travels on a first lane VC 1.
The environment analysis device MA of the vehicle V is responsible at least for acquiring and analyzing data representative of a zone ZA located in front of the vehicle (V) to detect obstacles OB and in particular living bodies (people and animals), and for estimating the relative position of the Obstacles (OB) with respect to the associated coordinate system of the vehicle V. For example, the analysis device MA may comprise at least one digital camera. However, the analysis device MA may comprise at least one infrared camera, at least one radar, or at least one scanning laser.
As shown in fig. 1, the illumination apparatus DE is mounted on the front of the vehicle V. Here, the illumination apparatus (DE) is mounted on the right front portion of the vehicle V. However, the illumination device DE may be mounted on the left front portion of the vehicle V. It should be noted that the vehicle V may also include two lighting devices DE mounted respectively at the right front and left front. The lighting device DE may also be mounted centrally in the front of the vehicle V (e.g. on a radiator grille).
As shown in fig. 2, the lighting device DE according to the invention comprises at least a first light source S1 and a second light source S2, a reflector RP, a lens LF, and a control means MC.
At least first and second light sources S1, a reflector RP, a lens LF are mounted in the inner space delimited by the housing BD and a transparent cover glass GP, which is located at the interface with the outside contact and through which the photons emerge.
The first light source S1 is responsible for generating first photons (shown as dashed lines in fig. 2) directed towards the mirror RP.
The first light source S1 includes, for example, at least one light emitting diode (or LED). As a modification, the first light source S1 may include at least one laser diode, gas laser, or lamp (or bulb).
It should be noted that the first light source S1 may optionally be mounted on a heat sink that facilitates the dissipation of the heat generated by the first light source S1 when it generates the first photons.
It should also be noted that in the non-limiting example shown in fig. 2, the first light source S1 is mounted on the upper portion PS of the reflector RP. This is not necessary, however. In fact, in an implementation variant, the first light source S1 may also be mounted at the lower part of the reflector RP.
The mirror RP is arranged to reflect the first photons generated by the first light source S1 towards the protective glass GP and the zone ZA so that they form a first light beam F1 which ensures a so-called primary photometric lighting function.
For example, the primary photometric lighting function can be selected from the group consisting of a low beam function, a fog light function, and a high beam function. In this case, the lighting device DE forms a headlight (or headlight).
For example, the mirror RP may define a complex surface based on a parabolic shape, as is known to those skilled in the art. Such a surface may for example consist of a sector of a substantially rectangular shape.
The second light source S is mounted in front of the central part PC of the reflector RP and is responsible for generating second photons (shown in solid lines in fig. 2) directed towards the lens LF.
The second light source S2 includes, for example, at least one light emitting diode (or LED). As a variation, the second light source S2 may include at least one laser diode, gas laser, or lamp (or bulb). When the second light source S2 includes a plurality of light emitting diodes, the light emitting diodes are preferably substantially flush in the vertical direction Z. In this case, the second light source S2 is installed in a vertical position with respect to the central portion PC of the reflector RP.
It should be noted that the second light source S2 may optionally be mounted on a heat sink that facilitates the dissipation of the heat generated by the second light source S2 when it generates the second photons.
It should also be noted that the mirror RP may be arranged such that its central portion PC does not participate in reflecting the first photons. It should be understood in practice that the presence of the second light source S2 in front of the central portion PC does not ensure a constant reflection function for the central portion PC.
In addition, as shown in non-limiting fig. 2, the central portion PC may be configured to define a recess RS that receives the second light source S2. At least in this case, the second light source S2 may be securely connected to the central portion PC.
A lens LF is interposed between the second light source S2 and the zone ZA, upstream of the protective glass GP, with respect to the propagation direction of the photons moving outwards. The lens LF can be positioned at different positions pk with respect to the mirror RP and forms, by means of the second photons generated by the second light source S2, a second light beam F2, the second light beam F2 being narrow and directed towards a sub-area of the area ZA which varies as a function of the lens position pk determined by the control means MC.
The lens LF is, for example, of plano-convex aspheric type.
The second light source S2 and the lens LF thus jointly ensure an auxiliary photometric lighting function of the marker lamp type.
The control device MC is configured to: when an obstacle OB is detected in a sub-area of the area ZA whose position is known with respect to the coordinate system of the vehicle V, the lens position pk is determined. The position of the sub-area is provided by the environment analysis means MA.
Therefore, when the brightness level outside the vehicle V is below a predetermined threshold value, and an obstacle OB is detected at a specific position in the zone ZA, the control device MC determines a lens position pk that allows formation of the second light beam F2, which second light beam F2 is narrow and directed to a sub-zone of the zone ZA that includes the position of the detected obstacle OB (see fig. 1). The lens LF is then immediately placed in the lens position pk so that the second light beam F2 illuminates the sub-area and thus the obstacle OB located in the sub-area.
Three different non-limiting examples of lens positions pk (here k 1 to 3) are schematically shown in fig. 3, which allow to illuminate obstacles detected at three different positions in front of the vehicle VA, respectively. In this example, the lens LF is angularly displaced along an arc of circle shown with dashed lines — dots.
It should be noted that in order that the lens LF does not obstruct all or part of the first light beam F1 at some of its lens positions pk during operation, it is advantageous that the control means MC determine the lens position pk away from the pass trajectory of this first light beam F1 to "park" the lens LF when the second light source S2 does not generate second photons. It will be appreciated that this allows the lens LF to be "set aside" when the marker light function is not in use.
The displacement of the lens LF can be done in different ways and in particular by means of the support SL and the motor ME. More specifically and as shown in non-limiting manner in fig. 2, the lighting device DE may comprise a support SL fixedly connected to the lens LF, and a motor ME driving a shaft AX fixedly connected to the support SL to rotate. In this case, the control device MC determines the angular position of the axis AX, which varies according to the known position of the sub-region containing the detected obstacle OB, and defines the lens position pk. It will be appreciated that once the control device MC has determined the angular position of the axis AX suitable for the known position of the obstacle OB, it triggers immediately the movement of the axis AX into this angular position, which simultaneously moves the lens LF into the lens position pk allowing the second light beam F2 to illuminate the obstacle OB.
The motor ME may for example be of the stepping type.
Furthermore, in the non-limiting example shown in fig. 2, the support SL passes below the mirror RP, however, in a variant of embodiment, the support SL may also pass above the mirror RP.
It should also be noted that in the example shown in non-limiting manner in fig. 1 and 2, the control device MC is installed in a computer CA of the vehicle V, which optionally ensures at least one other function. The control means MC may however comprise its own computer and may alternatively be accommodated in the housing BD. The control means MC may therefore be made in the form of software modules (or information modules, or "software"), or in the form of a combination of software modules with electrical or electronic components (or "hardware").
By means of the invention, the lighting device DE ensures not only the main photometric lighting function, but also an auxiliary photometric lighting function of the marker lamp type. Therefore, the volume and weight of the illumination device DE are only slightly larger than those of an illumination device without a marker lamp function. Furthermore, the integration of the two photometric functions in the same lighting device DE allows the use of a common supply and control harness for both photometric functions, without affecting the styling of the vehicle.
